Method Summary

Modifier and Type	Method and Description
static int	dimensions(Node node) Returns the number of dimensions for the specified node, eventually recursing up to find the parent node that has the indication of the dimensions (normally the top-most geometry element has it, not the posList).
static SimpleFeatureType	featureType(XSDElementDeclaration element, BindingWalkerFactory bwFactory) Turns a xml type definition into a geotools feature type.
static CurvedGeometryFactory	getCurvedGeometryFactory(ArcParameters arcParameters, GeometryFactory gFactory, CoordinateSequence cs) Returns a curved geometry factory given the linearization constraints, the original factory, and a coordinate sequence representing the control points of a curved geometry
static SimpleFeature	parseFeature(ElementInstance instance, Node node, Object value, FeatureTypeCache ftCache, BindingWalkerFactory bwFactory) Utility method to implement Binding.parse for a binding which parses into A feature.

Method Detail

parseFeature

public static SimpleFeature parseFeature(ElementInstance instance,
                                         Node node,
                                         Object value,
                                         FeatureTypeCache ftCache,
                                         BindingWalkerFactory bwFactory)
                                  throws Exception

Utility method to implement Binding.parse for a binding which parses into A feature.

Parameters:

instance - The instance being parsed.

node - The parse tree.

value - The value from the last binding in the chain.

ftCache - The feature type cache.

bwFactory - Binding walker factory.

Returns:

A feature.

Throws:

Exception

featureType

public static SimpleFeatureType featureType(XSDElementDeclaration element,
                                            BindingWalkerFactory bwFactory)
                                     throws Exception

Turns a xml type definition into a geotools feature type.

Returns:

The corresponding geotools feature type.

Throws:

Exception

dimensions

public static int dimensions(Node node)

Returns the number of dimensions for the specified node, eventually recursing up to find the parent node that has the indication of the dimensions (normally the top-most geometry element has it, not the posList). If no srsDimension can be found, check the srsName the same way and return the srsDimensions instead. Returns 2 if no srsDimension or srsName attribute could be found.

getCurvedGeometryFactory

public static CurvedGeometryFactory getCurvedGeometryFactory(ArcParameters arcParameters,
                                                             GeometryFactory gFactory,
                                                             CoordinateSequence cs)

Returns a curved geometry factory given the linearization constraints, the original factory, and a coordinate sequence representing the control points of a curved geometry
